A tower and a well and a ring and a river are all the same thing.
Wheelbreaker has several other planes of existence, accessible through a variety of methods and filled with all sorts of stuff. They're usually called realms and only some of them are real.
The normal realms are:
Discordant - This is where weird stuff lives.
Daemonic - This is where magic comes from and where the Fae live.
Physical and Metaphysical - This is where you live.
Etheric - This is where magic comes from and where the Fae live.
Astral - This is where weird stuff lives.
The Physical and Metaphysical realm is a single, compound realm. Prior to Lore™ the physical realm was separated from the metaphysical realms but they were forged into a single realm in a very messy affair that will be detailed in a later record. You may notice that the realms listed above Physical mirror the nature of those listed below, and this is because those realms are indeed mirrors of each other. The way in which they are a mirror is unclear and largely metaphorical but it is detectable and important for much ritual magic.
The realms Daemonic and Etheric (collectively referred to as the realms of magic) are places of thick woods through which rivers silently flow. If you get lost in just the way you may find any number of structures there, built by unknown hands and through unknown means, all of which are in ruins except for one. If you follow a river or creek long enough you may find folk living along the riverbed. These are the Fae Folk and they are friendly enough but it would be unwise to make deals with them or eat their food. If you are in the Daemonic realm then no matter what river you are following you will always find the same village with the same folks living there, although not all of them will be home when you pass through. If you are Etheric realm this will be the same also, but you will beet a different set of folk living in a different set of homes.
If you follow the rivers long enough you will eventually reach the start of the diver delta, and at this point there will be a large temple. At the heart of the temple is the manifestation of a god.
Beyond the realms of magic is either the Discordant or Astral realm (collectively referred to as the great ocean) where all the rivers in the realms of magic eventually flow. The great ocean lines the firmament of this realm, and the sky fills the remaining volume. Nothing have ever been recorded inside the sphere of the firmament other than a single island. The Isle of Arlus, as it is referred to by the uninitiated, is a small island covered in basalt cliffs and a hardy sort of clover. There is a single river delta from which all rivers in the realms of magic flow into the ocean simultaneously. Little is known of this realm, clover appears to be the only living thing in the realm, with the oceans being cold and completely empty. If you ever find yourself in this realm it is important to remember that no matter what you see, nothing swims in the great ocean's waters.
